Abstract

The objective of this study was to evaluate the quality of fresh cow’s milk from different farmers in Lampung Province as a raw material for cheese in view of the Indonesian National Standard SNI 31411 (2011) regulation.  Twelve fresh milk samples from four different districts (Tanggamus, Metro, Gisting, and Pesawaran) were evaluated by estimation of total protein and fat, pH, alcohol test, total plate count, antibiotic residues, and sensory. The result of the study revealed that the samples had protein and fat ranged from 2.44 to 3.90 %, and from 3.48 to 4.73% (wet basis) respectively.  The fresh milks had normal sensory and pH, negative of alcohol test, and free from antibiotic residues. Total microbes were detected in log 5-6 CFU/ml.  Majority of the samples screened met the Indonesian National Standard and could be used as a raw material for cheese making.  Keywords:  cheese,  fresh milk quality, Lampung province, SNI 31411,

Abstract

Efforts that can be made in clarifying copra oil made by the smoking method are absorption by adsorbents such as activated charcoal, zeolite, and bleaching earth. The adsorbent can be used for decolourizing and deodorizing. This research aims to determine the characteristics of purified smoked copra oil using different absorbents. Copra oil is weighed properly and the weight is recorded. Each absorbent material as much as 5% (w/w) of oil is added to the oil which has been heated at 70°C. Purification was carried out for 2 hours at a temperature of 70-75°C. The purification process is carried out in one stage. The oil is then filtered using filter paper (separating absorbent material and pure oil). The oil obtained was then subjected to free fatty acid (ALB) and organoleptic analysis. Based on the research results, purification with zeolite adsorbent resulted in the largest ALB reduction with a decrease value of 39.71%. Judging from the organoleptic characteristics, zeolite can significantly reduce the intensity of the brown color, the intensity of the coconut aroma, and the intensity of the rancid aroma. Activated charcoal can significantly reduce the intensity of the brown color, the aroma of smoke, the distinctive aroma of coconut and the rancid aroma of copra oil, while bleaching earth provides a marked reduction in the intensity of the brown color of the oil which at the same time provides a significant increase in oil clarity. The use of absorbent materials can affect the characteristics of smoked copra oil so that it has the potential to improve the quality of smoked copra oil.
